By the way, is there a reason 2p games are weighted so low with just 3p for the winner? The averages are (assuming you get each position with same likelihood in the games):
2p - 1.5 points per player
3p - 2.33 points per player
4p - 2.5 points per player
To me it would seem 4/0 points would be nice for duels. Still average would be 2/player, lower than 3er/4er. Now duel performance is a tad underrated in comparison.
